Maria has decided to invest to help with her retirement savings. How much would she have to invest to have $113,400 after 20 yea

Ipatiy [6.2K]

Answer:

$56,226

Step-by-step explanation:

x = investment

Earning interest of 3.57% is the equivalent of multiplying the initial balance (investment) by 1.0357;

Over 20 years, the new balance can be found by multiplying the initial balance by (1.0357)²⁰;

We can formulate an equation to solve to get the initial investment:

x(1.0357)²⁰ = 113400

(2.01687752)x = 113400

x = ¹¹³⁴⁰⁰/₍₂.₀₁₆...₎

x = 56225.5263 → 56226

Yoshiko collected some bottle sto be recycled. Twelve were brown. There were 50 more clear bottles than brown ones. There were 3

snow_lady [41]

So we know there are 12 brown ones
brown=12
50 more than 12 is the number of clear bottles so 50+12=62

brown=12
clear=62

30 numbers down from 62 is the number of green ones so 62-30=32

brown=12
clear=62
green=32

12+62+32=106

so Yoshiko collected 106 bottles
